setState() or markNeedsBuild() called during build. #9

Closed webaddicted closed 3 years ago

webaddicted commented 3 years ago

When I get app then it show error.

======== Exception caught by foundation library ==================================================== The following assertion was thrown while dispatching notifications for FeedProvider: setState() or markNeedsBuild() called during build.

This _DefaultInheritedProviderScope widget cannot be marked as needing to build because the framework is already in the process of building widgets. A widget can be marked as needing to be built during the build phase only if one of its ancestors is currently building. This exception is allowed because the framework builds parent widgets before children, which means a dirty descendant will always be built. Otherwise, the framework might not visit this widget during this build phase. The widget on which setState() or markNeedsBuild() was called was: _DefaultInheritedProviderScope value: Instance of 'FeedProvider' listening to value The widget which was currently being built when the offending call was made was: BlocBuilder<NewsFeedBloc, NewsFeedState> dirty state: _BlocBuilderBaseState<NewsFeedBloc, NewsFeedState>#b5032 When the exception was thrown, this was the stack:

0 Element.markNeedsBuild. (package:flutter/src/widgets/framework.dart:4328:11)

1 Element.markNeedsBuild (package:flutter/src/widgets/framework.dart:4343:6)

2 _InheritedProviderScopeMixin.markNeedsNotifyDependents (package:provider/src/inherited_provider.dart:269:5)

3 ChangeNotifier.notifyListeners (package:flutter/src/foundation/change_notifier.dart:243:25)

4 FeedProvider.setDataLoaded (package:inshort_clone/controller/provider.dart:68:5)

... The FeedProvider sending notification was: Instance of 'FeedProvider'
